Market outcomes
| ITF Szentendre: Yannik Kelm vs Trisztan Gubi | 100% YES | 0% NO |
| Completed Match | 100% YES | 0% NO |
Yannik Kelm faces Trisztan Gubi in the ITF Men's Szentendre tournament, scheduled for 3 June 2026. The match was originally set for 5:30 AM ET. Polymarket's order book currently reflects a 100% implied probability for resolution, indicating the market has priced in near-certainty that the match will be completed and a winner determined by the 10 June settlement deadline. This extreme probability typically emerges when either the match has already concluded or market participants view cancellation or extended delay as negligible risks.
ITF Futures events at the Szentendre venue historically proceed on schedule absent severe weather or facility disruptions. Both players competing at this tier rarely withdraw absent injury, and the seven-day grace period built into the resolution criteria provides substantial buffer against minor scheduling delays. The current 100% reading suggests traders have observed either match completion or confirmation of stable tournament conditions that eliminate meaningful tail risks around non-completion.
Traders monitoring this market should track any official ITF or tournament communications regarding weather forecasts, venue access, or player withdrawals through to the settlement window close. Hungarian summer weather patterns and court availability at Szentendre could introduce friction if conditions deteriorate significantly. The order book's current extreme probability leaves minimal room for repricing unless material new information emerges—any announcement of cancellation or extended delay would force rapid repricing toward the 50-50 tie resolution.
This market settles from the official outcome published at https://www.itftennis.com/en/tournament-calendar/. A proposer submits the final result to the UMA optimistic oracle on Polygon; the two-hour dispute window closes and payouts clear in USDC.
